[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-6725) Bidirectional @OneToOne(optional=true) with a foreign ID generator should force optional=false

Bidirectional @OneToOne(optional=true) with a foreign ID generator should force optional=false ---------------------------------------------------------------------------------------------- Key: HHH-6725 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6725 Project: Hibernate Core Issue Type: Improvement Reporter: Gail Badner Assignee: Gail Badner Fix For: 4.1.0 When a foreign ID generator is used with @OneToOne(optional=true), Hibernate should: - force optional=false - log a warning The default for @OneToOne is optional=true This should be done when a foreign ID generator is used - with @OneToOne @PrimaryKeyJoinColumn - with @OneToOne(mappedBy="...") Currently, Hibernate allows the one-to-one association to be optional, but if the association is set to null, IdentifierGenerationException is thrown. I don't think it's possible to check for a ForeignGenerator until the SessionFactory or persister is being built with a Configuration object.
